CONSUMER and electronics products distributor Wo Kee Hong (Holdings) is widening its product portfolio to include diesel generators and systems. Vice-chairman Richard Lee Man-fai said the company was finalising a deal to clinch the distributorship for a Japanese brand of generator and system. He said Wo Kee Hong would be granted the right to sell the products in Hong Kong, Macau and China. ''The diesel electricity generators, from small to large in size, are mainly for commercial and industrial uses,'' he said. Mr Lee said the markets for these products had tremendous potential for growth, especially in China, which faced a shortage of electricity to cope with its economic development. He said the sale of electricity generators would complement the group's distribution of air-conditioners. ''When clients in China buy our air-conditioners, they may need electricity generators as back-up. We can market and sell air-conditioners and electricity generators in a package,'' he said. Wo Kee Hong is prepared to set up a division for the distribution of the generators. ''It's a major development for the company. We wish to develop the distribution business of electricity generators to a size as big as our air-conditioners division in the long run,'' Mr Lee said. Wo Kee Hong mainly distributes audio-visual equipment and air-conditioners. It has diversified into car and car accessories distribution and the sale of satellite receivers. Mr Lee also said the group had just secured the sole distributorships to sell speaker systems for US brand Apogee and Canadian brand Totem in Hong Kong, Macau and China. It had also been awarded distributorships for compact discs for the Connoisseur Society of the United States, he said. To further enlarge its business portfolio, Mr Lee said Wo Kee Hong planned to launch a ''closed-circuit cable television'' service in Hong Kong and China. He said such a service was similar to video broadcasting services in hotels, but the group would initially introduce its service to serviced apartments. ''For that service, we will install a control centre in the targeted building. Then a variety of laser disc programmes such as movies or karaoke songs will be made available to the property's households,'' he said. He said it was negotiating with major property developers to install such services into their developments. The group has recently opened after-sales service centres in Shenzhen, Xian and Haikou. Similar centres would be established in Chengdu, Dalian, Wuhan and Fuzhou, he said.
